Can someone explain ROOT, PREV(PREV) and FROM(FROM) to me?

CB Scopes are horrible.

This & FromFrom =Third party character or third party title (depends on if you are in a character or title section)
From = Recipient of war
Root = Actor of war

So you do something like

FROMFROM = {
              save_event_target = attacker
}
...
attacker = {
...

Why is this better than just nesting an OR instead of a FROMFROM?

No you would do event_target:attacker = {

It is better because event_target:attacker always points to that one thing. FROMFROM means different things depending on what scope you are already in.

FROM = { FROMFROM = { points to FROMFROMFROM
ROOT = { FROMFROM = { points to FROMFROM
event_target:attacker = { always points to whatever scope attacker was saved to point to, in this case FROMFROM.

Hence it is better to use event targets as they are not ambiguous about what they point to as they are not context sensitive like the base scopes are.
